Setting resizable false toggles resizable on dialog

e.dialog('option', 'resizable', false); does not disable the resizing but toggles it instead.

The call is delegated from _setData to _makeResizable which expects the argument as a string that describes the resize handles. Since 'false' is not a string it will be replaced with the default string 'n,e,s,w,se,sw,ne,nw'. Probably the delegated call should be made only when _setData value evaluates to true.

This can be worked around by first checking e.dialog('option', 'resizable') and calling it with false only if the return value is true.
